What percentage of the worlds “urban” population lives in these top 25 cities? What is their definition of urban with respect to greenhouse gasses? Is it the same as urban population, or are there more/less stringent requirements to be an urban GHG?


> Key findings >1. The top 25 cities accounted for 52% of the total urban GHG emissions. 2. Cities in Europe, Australia, and the US had significantly higher per capita emissions than cities in developing areas. 3. Stationary energy and transportation were the two main sources of emissions. 4. Of the 42 cities that had time-series traceable data, 30 decreased the annual GHG emissions over the study period. Though in several cities, there was an increase in emissions. 5. 113 out of the 167 set varying types of GHG emission reduction targets, while 40 have set carbon neutrality goals.


Tell those mega cities to knock it off. There, solved.


I wonder how it breaks down between: Highly urban Developed Cities like Tokyo, Shanghai, Seoul, Osaka… and less developed/developing cities like Delhi, Sao Paolo, Dhaka, Mumbai… and more industrial cities like Shenzhen, Quingdao, Tianjin, Guangzhou… I also wonder how major American cities measure up. Especially per capita. We often forget on this side of the world that our Mega cities, NY and LA, are actually small by comparison. New York is like the 45th biggest city in China he world now. LA isn’t even in the top 100. Granted this might change a little when you adjust for the “greater area” vs that of some other cities.


“Just 25” what in the ridiculous headline
